Bulk resveratrol Supplier:

We have three types of Bulk Resveratrol Powders. One is micronized resveratrol powder. One is water soluble resveratrol powder and natural resveratrol powder with assay of 50%, and 99%. Our micronized resveratrol is made into tiny particles of 2-10 microns using a matrix grinder, which increases the absorption area by 1000 times. Water soluble resveratrol is molecularly encapsulated.  We also offer in specifications of 50% and 99 %bulk natural resveratrol. Guanjie Biotech is a resveratrol manufacturer, we offer high-quality products. Welcome to enquire: info@gybiotech.com.

Micronized Resveratrol COA

Sources

Resveratrol comes from a variety of sources; Guanjie Biotech's bulk Resveratrol Powder come from tiger nuts and grape skins. Here's a look at the specifics.
● Grapes:
Resveratrol is more abundant in grapes. Especially in grape skins. During fermentation of red wines, the skins are in contact with the grape juice for a long time. Some of the resveratrol dissolves in the wine, which is one of the reasons red wine is considered to have some health benefits.
● Pohygonum cuspidatum :
Pohygonum cuspidatum is a traditional Chinese herb. Reynoutria japonica contains high levels of resveratrol.
● Peanuts:
Peanuts are also a source of resveratrol. Studies have found that peanut red coat contains some amount of resveratrol. Although the amount is relatively low, it does provide a potential source for resveratrol extraction.
● Mulberry:
Mulberries are rich in nutrients, which also include resveratrol. The resveratrol content of mulberries varies depending on factors such as variety, origin, and ripeness.

● Other plants:
In addition to the plants mentioned above, resveratrol is also found in many other plants, such as blueberries, raspberries, and cacao. The resveratrol content in these plants is relatively low, but they do provide some supplement to the sources of resveratrol.

Chemical Properties

● Molecular Structure
The chemical name of resveratrol is 3,4',5-trihydroxy-trans-stilbene. Its molecular formula is C₁₄H₁₂O₃. The molecular structure of resveratrol contains two benzene rings and a vinyl group, which has strong antioxidant activity.
Resveratrol exists in both cis and trans isomers. Among them, trans-resveratrol is more biologically active. In nature, resveratrol mainly exists in the form of trans isomer.

● Physical Properties
Bulk Resveratrol Powder is a Brown or White Fine Powder (related to purity), odorless or slightly astringent. It has a melting point of 256-258°C and a boiling point of 449.1°C. Resveratrol is soluble in water. The solubility of resveratrol in water is low. However, it has higher solubility in organic solvents such as ethanol and methanol.

Resveratrol has a certain degree of photostability and thermal stability, but its stability decreases under strong light and high-temperature conditions. Therefore, direct sunlight and high-temperature environments should be avoided when storing and using resveratrol powder.

● Chemical stability
Resveratrol is relatively stable under acidic and neutral conditions but is susceptible to oxidation and degradation under alkaline conditions. In addition, resveratrol is easily oxidized by enzymes such as oxidases and peroxidases, thus losing its biological activity.

Applications:

● Healthy Food Market
With the increasing health concerns, the health food market is showing rapid growth. As a natural antioxidant and nutritional supplement, resveratrol powder is added to various health foods. Such as health food, functional food, beverage, and so on. This can meet the consumer demand for healthy food. For example, resveratrol can be added to fruit juice to make fruit juice drinks with antioxidant effects. Resveratrol can be added to yogurt to make yogurt with intestinal flora regulation and antioxidant efficacy.

● Cosmetic Market
Cosmetic market is also an important application field of resveratrol powder. Resveratrol has antioxidant, anti-inflammatory and whitening effects. It is used in various cosmetics. For example, resveratrol can be added to creams to make creams with antioxidant and anti-aging effects. Resveratrol can be added to serums to make serums with whitening and spot reduction effects.

● Pharmaceutical Market
Currently, there are already some resveratrol drugs under development, such as those for the treatment of cancer and cardiovascular diseases. However, the development of resveratrol as a drug is still at an early stage, and further research and clinical trials are needed to verify its efficacy and safety.

Safety：

Resveratrol powder is safe in general. However, some adverse reactions may occur when used in high doses. Such as nausea, vomiting, diarrhoea and headache. Therefore, when using resveratrol powder, you should strictly follow the recommended dosage and avoid overdosage.
For special populations such as pregnant women, lactating women, children, etc., there is not enough research data to show the safety of resveratrol. Therefore, these populations should avoid the use of resveratrol bulk powder.
